Q: What are the advantages of MPLS, and do the S5850 series switches support it?

A: MPLS (Multi-Protocol Label Switching) is generally a function required by operator customers and is very suitable for multi-point interconnection. Operators can leverage MPLS to create tunnels for their users, helping to establish point-to-point connections and reliable transport. FS currently provides LIC-FIX-MA licenses (software installation packages) for S5850 series switches to support MPLS and VXLAN-BGP-EVPN advanced functions, which can be purchased directly.

If you have requirements for MPLS features, you can choose the following S5850 series switches: S5850-48T4Q, S5850-48S6Q, S5850-24T16B, S5850-24S2C, S5850-24S2C-DC, S5850-48S8C, S5850-48B8C, S5850-48S8C-DC, S5850-32S2Q, S5850-48S2Q4C.

Q: Do S5850 series switches support MacSec?

A: The MACsec feature can protect the transmitted Ethernet data frames, reducing the risk of information leakage and malicious network attacks. FS S5850-24T16B, S5850-24T16S and S5850-24S2Q support the MacSec feature, which can help you achieve stricter data protection during network construction.

Q: If switches only do MLAG, what management software supports configuring each switch individually?

A: Based on the SNMP protocol, the FS switch uses the open-source software Zabbix to provide unified monitoring services for the switch. The FS switch also supports RPC-API and provides standard RPC-API interfaces to realize automatic operation and maintenance management.

Q: If RoCE performance is used for cluster storage using CEPH, is there a better solution for S5850 series switches?

A: RoCE provides the efficient, low-latency, lossless transport required for modern data center applications. ECN and PFC are the key technologies to achieve low-latency, lossless transmission. All S5850 series except S5850-24S2Q support ECN/PFC, which can achieve RoCE performance. Additionally, all Mellanox NICs provided by FS switches support ROCE.

Q: Can LACP or other LAG protocol servers be used after MLAG is configured?

A: When the switch is configured with MLAG, the server port is also configured with standard LACP to ensure that the link can be connected normally, which means that your server can use LACP or other LAG protocols for server devices to connect to MLAG devices through the LAG.

Q: How to connect S5850-48T4Q to S5800-48T4S via 10G MMF?

A: Please note that the S5850-48T4Q switch does not have 10G SFP+ ports, so the 40G ports have to be split into 4x10G ports (the command is split interface eth-0-1 10giga, and reboot takes effect). Then you can provide SFP+ ports through the conversion module, which can connect 10Gb MMF modules. Of course, the 10G SFP+ port of the S5800-48T4S can also use MMF optical modules.

Q: Can S58 series switches use MLAG and STP functions at the same time?

A: MLAG and STP functions can't be used together in S58 series switches.

FAQs about Power Supply

Q: What are the DC power supplies of the S5850 series switches?

A: There are three main types of S5850 series switches with DC power supply features: S5850-24S2C-DC, S5850-24S2Q-DC, and S5850-48S8C-DC. The power supply can support customized service, you can choose AC or DC power supply according to your needs.

FAQs about Comparisons

Q: What is the difference between S5850-48T4Q and S5850-48T4Q-PE switches?

A: FS S5850-48T4Q and S5850-48T4Q-PE switches have excellent hardware design, combining 48x100/1000M/5G/10GBASE-T ports and 4x40Gb ports. They come with complete system software, comprehensive protocols, and applications, which facilitate the rapid deployment and management of traditional Layer 2 and Layer 3 network services. The biggest difference between the S5850-48T4Q and S5850-48T4Q-PE switches is the airflow direction control. The former is the wind direction from front to back, and the latter is the wind direction from back to front, which can meet your different needs for wind direction.

Q: What Are the Differences Between S5850-24S2C-DC and S5850-24S2Q-DC Switches?

A: The FS S5850-24S2C-DC switch has 24x 10G SFP+ ports and 2 100GxQSFP28 uplinks to meet the needs of next-generation metro and enterprise networks. The S5850-24S2Q-DC switch has 24x10Gb SFP+ and 2x40Gb QSFP+ uplinks, which are more suitable for large campus network aggregation and small and medium-sized networks.

Q: What are the Differences Between S5850-48S8C and S5850-48B8C Switches?

A: The difference between the two switches is mainly in the ports. The S5850-48S8C has 48x 10G SFP+ ports and 8x100G QSFP28 uplinks. The S5850-48B8C has 48x25G SFP28 ports and 8x100G QSFP28 uplinks, which can aggregate higher bandwidth downlinks. And the S5850-48B8C upstream port can support 100G QSFP+ to 4x25G SFP28 DAC and AOC cables.
